Open Question: without my gaps will my lisp go away?

I'm in the 8th grade and i have a lisp.ive had it all my life and my cousin brought it to my attention when i was in third grade so i have been aware of it for a while. my lisp isn't your everyday lisp. my tongue doesn't leave out of my mouth it just touches my teeth from the back. i have a few gaps and an overbite, so i guess I'm wondering when i get my gaps closed and my overbite fixed will my lisp go away?
